SPECIFICATIONforming part of Letters Patent No 365,536, dated June 28, 1887.

Application tiled December 27, 1886. Serial No. 222,553. (No model.)

To all whom it may concern.'

Be it known that I, FRANCIS V. PHILLIPS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Door-Checks; and I do hereby declare that the following is a full, clear, and exact-description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which ro form a part of this specification.

This invention relates to a device Vwhich may serve both to fasten the door in its fullyclosed position or in a partially-opened posi# tion, or, in other words, one which may be x5 used either as a doorbolt or a door-check.

The invention embraces a two-part link having one of its parts hinged to the door and the two parts hinged to each other, a slide upon the outer part of the link adapted, in the closed position of the door, to be pushed outward beneath a lprojection on the doorjamb, with which it engages when the door is open in such manner as to be undetachable therefrom while the door is ajar, and a catch which holds thelink in its folded position against the door when the latter is closed, all spbstantially as set forth in the following description, and pointed out-in the appended claims. l i

In said drawings, Figure l shows the fastening in perspective view applied to a door and its frame and in action as a check. Fig.

2 is a front view of the device applied and acting as a bolt or fastening for the door when v closed. Fig. 3 is a horizontal section through the line 3 3 of Fig.- 2. Fig. 4 shows a modication.

A is a keeper having a vertical recess or depression, a, which is bounded by a projection, a, on the side adjacent to the door, and over which projects a horizontal and relatively narrow tongue, c, proceeding from the opposite side of said depression a. A space,

ai, is lprovided between the.` projection a and tongue a2, as shown in Fig. 3. The keeper A is desirably held vto the door-frame by screws inserted through the bottom` of the recess or depression a, as also indicated in Fig. 3 and less distinctly in Fig. 2. A 5o B is a two-part link composed of the rigid l parts B B2, hinged together by a vertical 'pivot at b, the hinge being set inward to allow the parts B and Bl to fold closely upon each other, as shown in Fig. 3. The part B 1s -hinged to the door by an outstanding pivot, b', 55 Asupported far enough outward from the face of the'door to allow said plate or part B to fold flatly against or parallel with the door, as also shown in'Fig. 3.

Upon the outer face of the part or plate B2 6o' of the jointed link B is tted a longitudinallyslidingplate, B3, provided with a slot, b2, near its outer end, of proper width to admit the tongue ai, said slot being closed by a cross,- bar, b3, at its outer extremity, which is wider than the thickness of the plate. The plate B3 is guided in its movement upon the plate B- of the link by any suitable conformation of the faces in contact, marginal Iibs b4 on the partB2 of the link being here shown for that 7o purpose, the plate B3 sitting down between said ribs against the face of the part B2. A. lengthwise movement of the slotted plate B: upon the part B'Z of the link is imparted by any suitable means, and desirably by means of a rotating button, C,.pivoted in the plate B2, and having an eccentric, c, which works in an opening, b5, through the plate B3. The button has a flange, c', which bears upon the outer surface of the plate. The object of the 8o lengthwise movement of theplate B3 is to enable the latter to be slid forward beneath the 'tongue a2 on4 the keeper A, as shown in Figs.

2 and 3, when the door is closed and the link is folded against the door, as also illustrated in'these figures, the space a3 being of only sufficient width to admit the` crossbar b3 flatwlse.

Adjacent to the central joint of the folded link when in the position shown in Figs. 2 970 and 3 is placed a catch, D, which is intended to engage 'the link and hold it rnily back against the door. This catch is preferably automatic in its action, and beveled and hookshaped, as indicated so that it will automatically engage the link when the latter is folded back. To thisend a dat spring, d, or one of any other suitable construction may be applied to the catch.

The opening a3, between the projection a Ioo and the tongue ai, is arranged to stand directly opposite the end of the sliding plate B3 when the door is closed and the link is in its backwardly-folded position, as best seen in Fig. 3.

Preferably, a plate, E, is provided as a support for both the hinge b and the catch D, in order that all the parts applied to the door may be connectedin their proper positions and together secured to the door by screws passed through said plate E, as shown. To prevent the outer part, B2, of the link B from swinging outward from its fellow, thc plateE may have a projection, e, Figs. 1 and 3,which will bear against said part BL at a point outside the line of the pivot b, and, as shown, this projection may be identical with the lug or lugs upon or between which the catch D is pivoted.

The operation of the device described is as follows: \Vhen the door is closed, the twopart link B is folded upon itself against the door and is held back by the catch D. lu this position of the link the sliding plate may be shot forward under the tongue ai, thus securing the door in its closed position so long as the catch D is retained in its engagement with the link, as in Figs. 2 and 3. To obtain the effect of a check which will stop the door in a partiallycpened position, as shown in Fig. 1, the sliding plate is first thrust forward beneath the tongue at of the keeper A, as above described, and after that is done the catch D is pressed back out of engagement with the link, and the door is opened. The itirst action resulting from opening the door is to swing the folded link outward 'from the door on the hinge b', by reason of the engagement of the crossbar b with the tongue ai. In this movement the cross bar b3 is rotated in the recess a, and the tongue a2 enters the slot b2. rlheuext action in further opening the door is to extend the link, as shown in Fig. l. The door will of course be permitted to open only to the length of the extended link. The crossbar b being of greater width than thickness, and the space ai* being only sufficient to admit said cross-bar flatwise, said bar will rotate in the recess a, but cannot be released from the keeper except when in the same position as when it entered, or, in other words,when the door is closed.

The holdingscrews which are set in the recess of the keeper are inaccessible when the crossbar b:s is in said recess, and the keeper cannot therefore be removed from the outside when the door is held partly open by the check.

Fig. 4 shows an obvious modification, in which the sliding plate B is T-shaped at its outer end, instead of being slotted, as in the preceding figures, and the keeper A is provided willi two tongues, a2, instead of one, which pass over the ends of the cross bar b3 instead of over the middle thereof. This inoditication is intended to be embraced in the appended claims.

l reserve the right to make future applica tion for patent upon any feature herein described or shown but not claimed.

I claim as my inventionl. The combination, witha two-part hinged link, one of which parts is hinged to the door, of a plate fitted to slide upon the other part of the link while held thereto and provided with a cross-bar at its outer end which is of greater width than thickness, and a keeper adapted to be secured to the door-frame having a recess bounded by a rib or stud onV the side thereof adjacent to the door, and provided with a tongue which projects from the oppo site side of the keeper over the recess and in position to engage the cross-bar, the space between the rib and the tongue being sufficient to admit the cross-bar of the sliding plate flatwise only, substantially as described.

2. rIhe combination, with a two-partjointed link, one part of which is hinged to the door and the other part of which is provided with a slide having a eross-bar at its outer eX- trernity. which cross-bar is of greater width than thickness, of a keeper provided with a recess, a rib or stud at the side of said recess adjacent to the door, and a tongue which pro` jects over said recess in position to engage the cross-bar of the slide, and a catch applied to the doorin position to engage the link when folded against the door, substantially as de scribed.

3. rIhe combination, with the keeper A, provided with a recess, a, rib or stud a', and tongue a2, of a centrally-hinged two-part link, B, adapted to fold upon itself, a slide, B, having a lengthwise movement on the part B2 of the link, and provided with a cross-bar at its outer extremity adapted to engage with the keeper, as set forth, a plate, E, for attachment to the door, having an outstanding hinged connection with the part B' of the link, a projection, e, at the opposite end of the plate E, in position to oppose the opening of the link when the latter is folded against said plate, and a spring-catch, also attached to the plate, in position to engage and hold the link in its folded position against the plate, substantially as described.

4. The combination, with the centrallyhinged two-part link flexibly joined to the door and with a recessed keeper provided with a rib or stud, a', and a tongue, a2, of a slide, B, provided with a cross-bar at its extremity of greater width than thickness and adapted to engage the keeper, substantially as described, and a rotatable button passing th rough the slide and pivoted in the subjacent part of the link, and having a lateral projection working in a hole in the slide to throw the same, substantially as described.

In testimony thatI claim the foregoing asmy invention I aliix my signature in presence of two witnesses.
